As mentioned, "Before Midnight" is the final installment of writer-directer Linklater's story about Celine (Delpy) and Jesse (Hawke), two strangers who met, and fell in love, on a train to Vienna almost two decades ago in the film "Before Sunrise." The sequel to "Sunrise," "Before Sunset," caught back up with Jesse and Celine nine years later in Paris, after Jesse had written a book about their encounter. In "Before Midnight," we find the couple in their early 40s, in Greece, taking on the hurdles of marriage and parenthood.

Hawke and Delpy not only star in the movie, they also co-wrote it with Linklater.
